Intelligent Protection & Classification of Transients in Two-Core Symmetric Phase Angle Regulating Transformers

17 Jun 2020Pallav Kumar BeraCan Isik

This paper investigates the applicability of time and time-frequency features based classifiers to distinguish internal faults and other transients - magnetizing inrush, sympathetic inrush, external faults with current transformer saturation, and overexcitation - for Indirect Symmetrical Phase Angle Regulating Transformers (ISPAR). Then the faulty transformer unit (series/exciting) of the ISPAR is located, or else the transient disturbance is identified... (read more)
